| dc.description.abstract | A thiadiazoloquinoxline-containing monomer, 8-(7-octyl-4,9-di(thiophen-2-yl)- [1,2,5]thiadiazolo[3,4-g]quinoxalin-6-yl)octanoic acid (74), was designed and synthesized starting from benzothiadiazole and oleic acid. An attempt was also made to synthesize a pyrazine-containing monomer, 8,8’-(3,7-dioctyl-5,10-di(thiophen-2- yl)pyrazino[2,3-g]quinoxaline-2,8-diyl)dioctanoic acid (73). The syntheses of the above donor-acceptor based monomers involved the preparation of 9,10-diketostearic acid via the oxidation of oleic acid using potassium permanganate as oxidant and condensation of this with 4,7-di(thiophen-2-yl)benzo[c][1,2,5]thiadiazole-5,6-diamine and 3,6-di(thiophen-2-yl)benzene-1,2,4,5-tetraamine, respectively. In the course of this work, attempts were made to synthesize 1,2-diketones via the benzoin condensation of substituted benzaldehydes and the Sonogashira reaction of arylbromides and 1-octyne. All intermediate compounds and products were characterized by spectroscopic methods including NMR, FT-IR and UV-VIS. | en_US |
